Custom Mini SAP Installation
The following guide can help you install Mini SAP 4.6D manually. That is, you can specify the SAP Idenfifier (<SID>) you want, the directory where you want to install Mini SAP and basically control the installation.
Here you will also learn that you can set up multiple instances of Mini SAP on the same machine as long as you have the appropriate hardware (enough disk space and RAM >= 256MB).
To illustrate the custom installation the <SID> RDV will be used throught the guide.
Here are the steps:
1. Copy the “R3SETUP” folder from the CD to your local drive.
2. Remove the “read-only” attribute on the template file MBS.R3S. Then, rename it to the new <SID>. Example: ren MBS.R3S RDV.R3S
3. Use Notepad or SAPpad and edit the installation template file (e.g. RDV.R3S). Change the following statements:
MBS_DIR=C:\RDV
Found under [MBS_PARAMETERS]
DB_SID=RDV
Found under [DBCOMMONDBENV_IND_MSS]
SAPSYSTEMNAME=RDV
Found under [CENTRDBINSTANCE_NT_IND]
sp_attach_db ‘RDV’, ‘@MBS_DIR …
Found under [ATTACHDBLIST]
DESCRIPTION=Start SAP RDV
Found under [PISTARTMBS]
MENUPATH=Mini SAP Basis (RDV)
Found under [PISTARTMBSGROUP]
10_DESCRIPTION=Start SAP RDV
30_DESCRIPTION=Uninstall SAP RDV
Found under [PISTARTMBSGROUPLIST]
MSSQL_DBNAME=RDV
Found under [LIC_ENV]
SERVICENAME=sapmsRDV
Found under [R3MESSAGEPORT_IND_IND]
Optionally, you can tweak the memory settings for the Database and for R/3 (PERCENT_FOR_DB and PERCENT_FOR_R3 respectively –both found under [CALCRAM_NT_MSS]).
4. Run R3SETUP with the following parameters:
5. Enter location where you want to install Mini SAP:

6. Enter CD location:
7. Enter location of Data CD:
8. Click on Exit when finished:
9. Rename RUNMBS.CMD to RUNRDV.CMD
10. Edit RUNRDV.CMD and change the following lines 4, 7 and 8:
11. Edit DBENV.CMD and change lines 1 and 4:
12. Rename MBS_D00.PFL to RDV_D00.PFL
13. Edit RDV_D00.PFL and change line 1:
Optionally, you can change the Physical Memory allocation.
The default value is:
PHYS_MEMSIZE = 64
14. Edit DEFAULT.PFL and change lines 1, 4, 5 and 6:
15. Rename MBSCORR.CMD to RDVCORR.CMD
16. Edit RDVCORR.CMD and change line 4:
17. Edit DEFAULT.TPL and change lines 1, 4, 5 and 6:
18. Edit the SERVICES files under %systemroot%\system32\drivers\etc and make sure that TCP port 3600 is there:
Installing a 2nd Instance of Mini SAP on the same machine
Basically you need to repeat all the steps above using a new <SID>.
However, you need to change the instance number for the second system to 01. The file to edit is <SID>_D00.PFL (line 2, SAPSYSTEM=01).
Also, make sure that the “services” file under %systemroot%\system32\drivers\etc contains the appropriate TCP port for the new instance.
Example:
sapmsRPR 3600/tcp
Finally, do not forget to set the appropriate instance number in SAPLogon when creating an entry for the 2nd instance.
